Channel catfish, Ictalurus punctatus, swim-up fry were either stocked directly into prepared nursery ponds or fed a prepared diet in hatchery tanks for seven days prior to stocking in ponds to evaluate the effects of hatchery feeding on growth and survival in ponds. Two experiments were conducted during two growing seasons (1991 and 1992). Nursery ponds in both treatments were prepared and fertilized according to standard recommended procedures. Survival was significantly higher (P < 0.05) in fish not fed prior to stocking in both experiments. At harvest, there was no significant difference (P > 0.05) in average weight between treatments in either experiment. In experiment 1, total yield was significantly higher (P < 0.05) in fish that did not receive hatchery feeding. There was no significant difference (P > 0.05) in feed conversion ratio (FCR) in experiment 1. During experiment 2, FCR was significantly lower (P < 0.05) in fish not fed prior to stocking. Results indicate that stocking of channel catfish swim-up fry into properly prepared nursery ponds is a suitable method for fingerling production. |
